The Big Thaw: Exploring the Disappearing Antarctic Sea Ice

No comments
For week 30, we revisited a topic from 2018 week 15 - Arctic sea ice extent. During watch me viz, I focused on rebuilding:

  1. Visualizations from chapter 12 of the Makeover Monday book that showed how to add context to visualizations
  2. Several of the vizzes from 2018 week 15, each with their own unique take on the data
  3. The original viz by The Guardian
In the end, I created 13 visualizations before settling on the viz most similar to the original. There were some great questions today on the livestream. Thank you for that.

When you watch this video, you will definitely learn something new. You'll also learn a lot about how I think through problems when I run into them.

What is a KPI?

KPIs are measurable values that indicate how well a business is performing in achieving its key objectives and goals. They provide a clear and concise snapshot of critical areas within a business.


KPIs help to:

  • Monitor progress

  • Identify areas of improvement

  • Make data-driven decisions


In order to do this, KPIs must be tailored to specific goals and strategies.


Making KPIs Actionable

Here are 8 suggestions to ensure that KPIs are actionable and impactful.

  1. Align with business objectives

  2. Focus on relevance and simplicity

  3. Set measurable targets

  4. Collect accurate and timely data

  5. Visualize your KPIs

  6. Regularly review and update

  7. Add context

  8. Drill down


Actionable KPIs are vital for measuring performance and achieving results. You can drive your business forward by aligning data with goals and simplifying and visualizing KPIs effectively

How to Conduct Customer Retention & Cohort Analysis

No comments
In this tip, I’m going to show you how to analyze customer retention and conduct cohort analysis in Tableau.

With cohort analysis you group your users based on a shared characteristic to better track and understand their behaviors. Cohort analysis is typically used to understand customer churn or retention.

Cohort analysis is nearly always done for an app launch.
  • First, down the view, the users are divided into cohorts based on when they first installed the app
  • Then, across the view, the users are tracked for 10 days after the launch to see who continued to use it.

Comparing these two groups allows us to see when users are churning so that we can then investigate why.

How to Create a 3 Level Drill Down in Tableau

No comments

I've showed you in several videos and WatchMeViz live streams how to create a 2 level drill down. And naturally the follow up question is always, how can I go one level deeper? This tip has exactly what you're looking for. I show you how to create a 3 level drill down in Tableau.

This example shows you how to drill down from Category to Sub-Category to Segment. All you need to do for your situation is replace the dimensions I'm using with yours. This will work with any combination of 3 dimensions.

Check out the interactive version below the video.

This type is inspired by this example from Lindsey Poulter - https://public.tableau.com/app/profile/lindsey.poulter8872/viz/SetActionDrilldown/ChooseaMetric

#MakeoverMonday 2022 Week 40 - Income Inequality Around the World

No comments
Of course, as soon as I posted the data set this week, the UK PM decided to backtrack on the tax cuts she has promised before. In my opinion, this is a good. But it kinda made that part of the analysis irrelevant.

Still, though, I was curious to see how the UK compared to the rest of the World. During Watch Me Viz (below), I started by rebuilding the original chart, which I quite liked. I then looked at the data over time, but it was quite sparse and difficult to do any meaningful analysis of.

So I decided to stick with a single chart that looked like the original, but it includes all countries and some filtering options.

To learn how I approached the analysis and built the charts, watch the video below. My final dashboard is below the video.

Enjoy!

  2. Why the attribute aggregation exists 
  3. Examples that show how it works 
  4. The difference between ATTR and other aggregations like MIN & MAX

How to Use the Highlighter to Set a Default Color Palette

No comments
Let's say you have a view with lots of marks and you want highlight a specific mark and assign a color palette so that mark is always highlighted whenever that dimension is used, irrespective of the chart.

To do this you can Highlight one or more discrete fields from the color palette and assign those marks to be highlighted. This does not impact the level of detail in the view.

Here's how you do it:

How to Create a Two-Panel Column Chart

No comments
I this tip, I show you how to create a column chart that has one data series on the primary axis on one row and another data series on the secondary axis on a second row. Even though this is called a two-panel column chart (by Jon Peltier) there are two measure in the rows and one or more dimensions in the columns.

This might be my shortest tip ever, but I bet you'll find it useful.

Proportional Brushing with a Set Action

Proportional brushing allows you to view an item you choose from one chart as a proportion of another chart. For example, you can view the sales for Corporate (from the Segment dimension) as a proportion of the sales of each Region.

No comments

How to Create an Alternative to a Merimekko Chart

No comments

A Merimekko Chart, also known as a variable width bar chart, is useful for comparing both high-level data and low-level data in the same chart. However, since we have size variables for both the width of the bars AND the height of the bars, comparing different segments of the chart is more challenging than it needs to be. Read more about the problems with Merimekko charts here.

In this example, I show you how to make an alternative to a traditional Merimekko Chart. I show you how to compare both category sales and regions sales within each category at the same time.

This can be easily replicated by simply swapping out the dimensions and updating one LOD calculation. Alternatively, you could use two parameters to allow the user to pick both the high-level and low-level dimensions and a third parameter for the measure to compare.

How to Include Multiple Dimensions on the Color Shelf

No comments
In this tip, I show you how to include more than one field on the color shelp. 

A few notes:
  1. You can have more than two dimensions on the color shelf. Simply repeat the steps for adding a second color.
  2. This only works for dimensions, as I show in the video.
  3. You do not have to use Sets for this to work; I used that in my example for simplicity.
